Seagate Technologies, the original Shugart Technologies, once sold a two.25-inch hard drive using a capacity of only 5M at a cost of $ 1500. It now appears that the complete challenging disk industry is indeed steadily advancing in line with Shugart's words. Obviously, almost everything is now incredibly various from that time, let's take a closer look.
Magnetic storage hard drives are now in their 50s. In 1956 IBM launched the 305RAMAC disk storage method, which can be regarded because the originator of today's challenging disk. This disk storage technique is in regards to the size of a refrigerator and uses 50 double-sided two-foot-diameter disks to provide a total storage capacity of four.4MB. The storage density of this disc is 2000 bits per square inch, which translates to a price tag of 10 million dollars per GB.
Today's notebook difficult drives are usually 2.5 inches, only a deck of playing cards, can retailer as much as 160GB capacity, storage density is 131 billion bits per square inch, the price per GB is less than $ 1.
Last year, customers purchased greater than 700 million GB of difficult disk storage space, 11 times that of 2003.
As far as the Usa is concerned, in 2006, an external hard drive of $ 600 million was sold, a 53% raise from 2005.
In 2003, the price per GB capacity was about 2.04 US dollars, by 2006 this cost dropped to 77 cents
Information recording density, or capacity, has enhanced 60 million instances previously 50 years.
The world's data capacity in 2006 was 161EB, and it's estimated that by 2008 this quantity will reach 988EB. idoo usb encryption software is equal to a single million TB.
By usb encryption windows 8 , the total level of data will drastically exceed the total information storage capacity, about 2: 1 ratio. The worldwide information capacity in 2007 will exceed our storage capacity for the first time.
Study identified that on large IT equipment, the annual disc replacement rate will generally exceed 1%, reaching about 2-4%, and also 13% on some systems.
